MeerKAT TRAPUM survey


The MeerKAT TRAPUM survey (meerkat_trapum) published its results in 2021 with a total of 8 new pulsars discovered. It detected a grand total of 0 pulsars. The fastest pulsar discovered was J0024-7204ac with a period of 2.74 milliseconds and the slowest pulsar was J1910-5959F with a period of 8.48549 milliseconds. The smallest pulsar dispersion measure was J0024-7204ad with a DM of 24.41 pc/cc and the largest pulsar dispersion measure was J1748-2446an with a DM of 237.736 pc/cc. There were a total of 2958 pulsars known before the first discovery was published. This survey increased the total amount of known pulsars by 0.3%.

There was 1 paper written about the discoveries in this survey: Eight new millisecond pulsars from the first MeerKAT globular cluster census.
